#2With something as important as blockchain verification, you would think DARPA would stop investing in private intellectual property.

#3They keep using the word 'block chain'. Is that the same idea as the bitcoin blockchain?

Yes.

Why is blockchain 'important' to Darpa? Because you are rooting for bitcoin or for some other non-specific to you reason?

#6As far as I can tell from the article, they are using the same kind of technology which prevents people from falsifying their account balance on Bitcoin to prevent intruders from covering their tracks in a secure computer system.

Specifically, it's a Merkle tree. From what I can tell they're not using anything else relating to "blockchains".

Because it's a cryptographic proof. If their implementation is faulty they are vulnerable. It's very difficult to do correctly and many bugs have been found in bitcoin and other blockchain technology. This is pretty much one of the harder areas of computer security...

#9Guardtime is set of tooling around a FIPS 140 timestamping appliance. Systems on the network submit hashes of their logs to the time stamping. Assuming the appliance remains secure, you can go back in the event of compromise and prove that your logs are unaltered up to a certain point.
It's amazing that they seem to have built a $50 -$100 million dollar business here.

The blockchain is critical current & future technology, it's future is independent of Bitcoin's future.
Bitcoin is the first implementation of a blockchain system, but it's a technology, not Bitcoin.
All major log systems will be based on it; governments, banks, military, voting systems, etc.
Highly suggest reading the Wikipedia entry on Blockchain to learn more and think about how you might use it too: https://en.m.wikipedia.org/wiki/Blockchain_(database)
